For the past six to seven weeks, as I have perused every available reloading supplier available to me, both locally and on the internet. I haven't been able to find any reloading supplies for the .300 Remington Ultra Mag. Actually, I'm referring to brass and bullets over 180 grains. This suggests to me that there are a tremendous amount of folks that are loading for and shooting this exceptional caliber. I had a custom rifle built for me in this caliber and now I'm having regrets. It is the first specific long range shooter that I have ever owned. I have been trying to play with different powders and loads but, all of a sudden, every 200+ grain 30 caliber bullet is gone and brass has disappeared. So, I would like to know how many of you have done the difficult task to work up some great loads for long range shooting and would you like to share your findings with me and the rest of us? Oh, right now, my best load is 96.2gr of Magnum, 215 Federal primer and 200gr. Nosler Accubond loaded in Nosler brass. Out of my 30"barrel at 4320 ft. of elevation it's averaging 3286fps.
